How can i define symbolic term when using sysic?

Hi everyone,

I want to use symbolic term when using sysic in MATLAB. Please find below the small code.

syms dddelta % define dddelta as a symbolic variable instead of a constant

systemnames = [' dddelta '];

inputvar = '[ control ]';

outputvar = '[ dddelta ]';

input_to_dddelta = '[ control ]';

sysoutname = 'Actuator';

cleanupsysic = 'yes';

sysic

It does not work when I assign dddelta as syms. Any idea on how can i overcome the problem?

Thanks

Yashvin
